INCL, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK SLICING MACHINE Application filed November 16, 1928. Serial No. 319,988.

This invention relates to slicing machines and their appurtenances and more particularly to mechanism for regulating the thickness of slices of the object cut.

'5 The present invention aims to provide a device for regulating the thickness of the slices, which may be cheaply manufactured and will be simple in operation.

comprehensively stated, the invention comprises a regulating tray, some form of support and mechanism interposed between the support and the regulating tray for accurately raising and lowering the regulating tray in a plane which is substantially parallel to the cutting mechanism.

In its more specific aspect, the invention comprises a rotatable intermediate member which varies the distance between the tray and support when rotated.

While one embodiment of the invention is shown, it is to be understood that such illustrated embodiment is merely for the purpose of afiording a clear understanding of the underlying principles of the invention so '25 that they may be readily understood by those skilled in the art without limiting the invention to the precise details of construction shown in such drawings.

In said drawings Fig. 1 is a side elevation of the invention as applied to a slicing machine of the gravity feed type shown in the United States patent of Peter Sivertsen No. 1,67 7,497

Fig. 2 is an end elevation of the invention i as shown in Fig. 1;

Fig. 3 is a section of Fig. 2 on the line 83; Fig. 4 is a bottom view of the regulating tra 5 is a section of Fig. 4 on the line 55; Fig. 6 is a section of Fig. 4 on the line 66; and

Fig. 7 is a section of Fig. 4 on the line 7 7 Continuing now by way of a more detailed 7 description, the reciprocative feed carriage A for carrying the object to be sliced is adapted to be moved past a rotating knife B. A tray C for regulating the thickness of the slices is located adjacent to the knife B and lies in substantially the same plane as does the knife. While the plane of the knife is shown as inclined to the horizontal, it is to be understood that the present invention is not limited in its application to slicing machines of the gravity feed type but may be applied equally well to machines in which the knife is either horizontal or vertical.

The regulating tray C and its controlling mechanism finds its support on any suitable member, as bracket D, preferably affixed to the base of the slicing machine although manifestly, it is immaterial as to whether this support is so attached. The upper end of this supporting bracket is threaded at E to a stationary supporting member F, which principally for the sake of economizing Inaterial, has a plurality of outwardly extending arms F, the outer ends of each of these arms having an inclined slot F to slidably receive inturned cam faces G, which control the distance between the regulating member (to be described) and the stationary supporting member F, and are preferably formed of sheet metal having an inclination corresponding to the inclination of the receiving slots F. The cam faces G are arranged in proximity to the outer end of each of the arms F on a rotatable spacing plate H which has a plurality of openings H for permitting it to clear a plurality of upstanding guide pins J which are aiiixed to the lower face of the regulating tray and project through guide openings J in the stationary supporting member F. The guide pins J and openings J maintain the regulating tray in proper relation with the supporting member F and yet permit it to be raised and lowered by the action of the cams G. The rotatable spacing plate H is pivotally centered on a dependent pivot pin K projecting from the lower face of the regulating tray D. It is the rotation of this spacing plate and its attached cam faces which raises and lowers the regulating tray D with respect to knife B. The mechanism for rotating the plate H around the pin K consists of a rack L secured to or formed at one side'of the plate H and engaged by a pinion ii controlled by a suitably graduated hand operated finished member M. The rack is slightly arcuate so that on rotation of the spacing plate it will not lose contact with 100 pinion L. T he plate H is preferably a sheet metal plate having the upstanding cam faces G secured thereto by any suitable means although manifestly the cam faces G might also be formed directly from the material of plate H. The plate H, in addition to the pivotal support afforded it by the pin K, has its edges freely sliding in slotted lugs N depending from the regulating tray which permit the plate H to rotate and yet maintain it in parallel relation to tray D. In order that the rota ion of the plate H may be suitably limited so as to prevent separation of tray and plate, a stop screw P extends in the path of the edge of the plate H as will be readily understood. This screw is threaded in a dependent tlange formed with the regulating tray although its position or support is not necessarily as shown.

The device operates as follows :The member F because of its threaded engagement with the post D is relatively stationary. As the member M is rotated, it moves the rack L on an arc, the center which is pin K, as will be readily understood and swings the plate H around its pivot point K, the rotation of the plate H causing the inclined cam faces G to slide laterally in the inclined slotted openings F in the member F. As the slots F ride on the cam faces G the rotatable plate H is either raised or lowered with respect to the stationary member F and as the regulating tray is held to the plate H by the slotted lugs N, the tray will be raised or lowered at the same time that the plate H is raised or lowered. This raising or lowering of the regulating tray shifts its position in a vertical plane with respect to the knife edge to vary the thickness of the slices.

What I claim as my invention is:

1. A slicing machine combining a regulating tray to regulate the thickness of the slices, a stationary supporting member having a plurality of cam faces, means comprising a pin to guide the regulating tray, an intermediate member connecting the regulating tray and the supporting member, the intermediate member having a plurality of bent ears forming cam faces in interlocking engagement with the cam faces of the supporting member, and means to rotate the intermediate member so that the cam faces of the intermediate member will vary the distance between the supporting member and the regulating tray.

2. Means for regulating the thickness of slices in slicing machines combining a table movable transversely to the plane thereof, said table having a plurality of dependent lugs each having a guide slot a stationary supporting member secured to a slicing machine havmg extending arms each of which has an inclined guide slot, a dependent pin secured to the lower face of the movable table and sliding in an opening in the stationary member to prevent rotation of the table relatively to the stationary support, an intermediate rotatable plate sliding in the guide slots of the table lugs and having correspondingly inclined guide edges enga ing the inclined slots of the stationary mem er and means to rotate the intermediate member to cause the inclined guide edges of the intermediate member to move in the inclined slots of the stationary member to raise and lower llzahe table with respect to the stationary mem- 3. A slicing machine combining a regulating tray to regulate the thickness of the slices, a stationary supporting member having a plurality of cam slots,'means to guide the regulating tray, an intermediate member connecting the regulating tray and the supporting member, the intermediate member having a plurality of bent ears forming cam faces in interlocking engagement with the cam slots of the supporting memher, and means to move the intermediate member so that thecam faces of the intermediate member will vary the distance between the supporting member and the regulating tray.

In testimony, whereof, I have signed my name to this specification this 18th day of October, 1928.
